it' known that I, CHARLES' A; Lri'rnn- Hann, a citizen of the United States, residi panying drawings.

The invention has relation to the* devices 4whichare employed forthrowing the shuta loom, .and for checking it as it com- P6 tes itsv entrance into the shuttle-box at j f -Thc invention' comprises an improved construction of lugestrapg an improved constructlon .of picking-arm, and cushion-1n- 'termediate such arm` and the lug-strap; and

novel means coperatingwith. the lugstrap toeheck the shuttle at the' end of its fllght.

j. The improved lug-strapfcomprifses opposite loops, one thereof-for engagement with the I picking-arm and the v.other with` the picker-stick, said loops ldisposed inplanes at right angles to each other, and clamp- `members receiving ,on'four sides thereof the 'said/free. ends and coupling the .loops togather. `In the preferred embodiment of this portion' of the invention,thebv clampmembers v.clasp the yfree ends of one loop "edgewiselbetween' them,`an,d the free ends of 4the other loop are clamped flatwise to the said'clamp-members. j The construction provides for adjustment by which', the effective length of the lug-strap is variedl i I provide the picking-arm with a socket or holder, Withinwhich I place a block or pad of material softer than iron. The said block or pad is encircledrby a loop at the kinner end of the'lug-strap, and its use obviates the Wear which otherwise would be receivd by t e metal parts of the picking-arm and lug-strap iffthey were in` contact during operation.-

Various special features are embodied in the construction. of the picking-arm and its socket or holder, and in the combination of the block or pad therewith. One aim, in

particular, in this connection, is to enable old loom-pickers to be utilized to great a'dvantage.- Y

One characteristic of the shuttle-checking features of the invention4 is the employment of means intermediate the lug-strap and the picker-stick for absorbing theenergy transmittedv to the latter b the shuttle.

Another is the emp oyment-of'members in connection, respectively, with' the pickerstick and lug-strap, and offering frictional resistanceto the shuttle-imparted movement of thepicker-stick.

Another is that the vertically-acting weight of the lug-strap opposes the shuttleimptrted outward movement of the pickerstic Another is the` employment of adevice through.which the energy of the shuttle is absorbed in the work of,l lifting the. lugstrap. In the preferred embodiment -ofthis portion of the invention I employ an incline and a contact-member, one thereof moving with the picker-stick and the other connect-l ed with the lug-strap, the weight 4of the lug-strap holding them in contact and shuttle-imparted movement of the' picker- :stick producing relative movement'of said members lengthwise of the incline, and such relative movement operating to lift the lugstrap vThe drawings illustrate embodiments of the features of the invention., i

picking-*arm reoeives'in its bend or bight a part in connection with the picking-arm; the other loop embraces 'the picker-stick. The two loops are in planes at right angles to each other, so that when the lug-strapl is Vengaged with the clamp-members, the

lengths of the loops being suicient to provide for extension by adjustment Within the clamps and relative to each other to the maximum required length of lug-strap.

The clamping devices comprise two opposing clamp-members 24, 24, which receive the two end-portions of one loop, as 22, edgewise between. them, the said members having longitudinal flanges 25,25, which lie elongside the said end-portions and prevent them from slipping transversely out'of thegrasp of the clamp-members. The backs of the .clampmembers have formed therein grooves 26, 26, which receive the two end-portions ofthe other loop, in this case the loop 23, which lie flatwise therein. Washer-plates 27,. 27, lie against the outer surfaces of the end-portions in said grooves. A.A securing bolt 28 passes through holes 27 in the Washer-plates and also through holes in the loop-end-portions which occupy the'grooves, and through slots 24, 24, in the clamp-members. rlhe bolt receives a nut 29 on its threaded portion. By tightening up the bolt andf nut, the endportions last mentioned are claned .tightly in the grooves, and the end-porti s between the clamp-members are" clasped securely edgewise between the latter.- Thereby the parts of the lug-strap are secured .together in working'rclations and condition.

For the purpose of eiecting adjustments of the eli'ective length of the lug-strap, the bolt and nut are loosened, and the end-portions of loop 22 are shifted lengthwise be tween -the clamp-members, in addition lto which, the end-portions of loop 23 may be shifted lengthwise within the grooves of the' clamp-members within the' limits of the movement permitted the bolt lengthwise-of the slots in the clamp-members. The shift or adjustment of loop 22 relative to the clamp-members will usually afford all the' capacity for adjustment of the length of'the lug-strap that is required, so that in some cases the bolt-openings 'in the clamp-mem- -bers need not be elongated. To engage the clamp-members with each other'. so. as .to prevent them from becomin displaced relative to each other, each c amp-members@ of the lips of the other member.

It will be observed'that only. a single bolt and nut are Vemployed in the construction of the {lug-stra ,senil .that-only this bolt Zand l loosenedxandtightened in assembling the lug-strap. and adjusting Working length. Y

To prevent injury to the icker-.stick hy contact of the extremities .o fthe sidepo'r tions of loop A22 therewith, .one of such :ex-

tremities is left longer than the other and is bent vertically, 'as vat 225 so as to -lie across the opposite extrem-ity, covering and concealing the latterY and presenting the smooth outer surface of the bent extremity tow-ard the Zpicker-stick,

lThe cushion -or pad which is employed .in the-bender b ight of the outer loop 23 0f the -lugstrup for contact with the outer. edge of the icker-stick i's marked 32 in Figs. l, Land Y.lt is secured in place by a bolt 33 which passes transversely through holes in the sides-of xthe said loop and in the cushion or pad,'and has Ya nut efapplied to its" threadedend outside the-eonnespondin side of the. loop. Forreasonsnf .economy employ for the cushion or pad a' worn loomi picker of ,the well-known :loop form. In order to utilize Athe-entire picker and enable all. the substance .thereof to `be utilized for cushioning purposes,-1 fill the e eof the loop with' a plug 35, Fig. 5, whic may be either a lilac. t.o A The bolt which v.fastenhs the 1picker in place within loop ofthe lug-'strap passes t u'ough the-sloop-,pontion of the pickerand a: o .through this plug.

By causing the securing bolt to pass through the loop of the picker and the plug I am enabled to utilize the entire substance offihe body-portion ot thepicker as a'cushion between the plug and thepicker'stick.

`.'lhe-construction of the picking-arm and its -socket *or holder for the cushion that is applied thereto. in accordance with my inventi'on, and the form and material of the cushion, may vary. Reference will be made tirs't to' the parts as they are shown-in place 1n the loom in Figal; and detached 'in Figs.

13, 14 and '15. Only the detachable adjustablepart of the picking-arm is represented in the .latter figures, The socket or holder forine cushion 42 is at the lower end'of vthebsaid part.' Thesaid socket'or holder comprises a fixed ivall 37 and aA detachable- A sa' .p lace upon"the picking-'arm by .means of a bolt 39 which passes 'through holes in the.

Shanks of the .said Wall and arm abovethe said space,v and a nut 40 and Washer 41 applied to the said bolt. The socket or holder 1s constructed to support the cushion or padA 42a and "securelyv hold it in place during operation. The A:oppositewalls are 'provided -vvith projections 42, 42, Fig.`15, extending toward each other and shaped to form a stepped overlapping joint having vertical faces which make 'contact with each other vto cause such projections to properly register with each other, While permitting the walls to be separated more or less by cushionsor pads of different sizes. The cushion or pad has a hole which extends transversely therethrough and which receives the said projections. The projections sustain the cushion or pad against the resistance which it encounters frointhe surrounding loop of the lug-stra p when the picking-arm. is swung inward through the action of the picking .rockshaft Recesses-are formed' inthe two walls to receive the Jfront and rear sides of the'cushion or pad, the shoulders 44, 44, at

. j ilissjeee tical displacement of thecushion or pad bev tiveen the walls. v

Thccushion or padl :invconnection Withtlie picking-arm serves as a bulici between the-said arm and the bend or bight at 'the inner end of the lug-strap. The upper portion of the said bend f-orbight occupies the opening 45' above the cushion or pad, and when the lug-strap swings loosely it rests upon the top surface of the cushion or pad. When the pickiugaction takes place, the Contact and pressure occur against the inner end of. the cushion orpad. The einployment of the cushion or 'pad obviates wear between Vthe .picking-arm and the lugstrap.

The construction of socket or holder shown in Figs. 17 13, l-L and 15 is especially adapted to receive and emploiY as a cushion or-pad a loom-.picker of the kind knoivnas a loop-picker. The eye of the loop thereof constitutes the hole oi' opening which 'receives the proj cctions extending toward each other from the tivo walls, andthe outer portion .of the loop itself of the picker intervenes between-thc said projections .and the.-

embracing lugstrap loop. I vam thereby enabled to utilize the loop-pickers lwhich have served theirV purpose as pickers in l'ooms until they have becQine too far worn.

for further use in that service, with a very considerable economy and saving in the cost of maintaining and operating-looms. In the 'said construction the picker occupies a horizontal position, its loop being turned toward the middle of the loom to serve as the cushion.` its'Striking part containing the cavity Worn' by =contact with shuttle-tips being turned outward. f

I The picking-arm 21u shown in-JFgsIG,

17, 18, 1 9 and 20 has a vertical pocket 46 opening at the -side 'of such arm which is turned toward -the middle of the loom. The

. lower end ofthe picking-arm has an openbottomed slot 47 therein communicating with the said pocket, and above the said slot 'a hole. 48 is made through the outer wall of the picking-arm, such hole communicating with the upper portion of the pocket'.- The cushion or pad 42a occupies the said pocket.

The hole through the upper portion of the cushion' or pad registers with the *hole- 48 'in the- Vsaid outer wall. They upper sideportioniof theloop 22 of the lug-strap is in practice caused tp occupy the said Aregistering.` holes, and the lower side-portion of the said loop occu ies the slot. The bottom of Athe hole 48-in t e outer side-wall'of-the pickingarm is lower down' than the bottom of the --hole through' the cushion orpad, as shown in Fig. 19. Consequently 'the upper side-portion ofthe said loop of 'the lugfstrap rests upon the bottom of the hole in the "wahoutcontcting"with the The' said holeB in the picking-alim Ais wider vi-ed on the cover is broken erence to Figs horizontally than the hole 'through the cush-- ion or pad, asjshown in=fFig`.f16,-and conse-y quently the edges of'the'saidupperportion of the 'loop .of the lug-strap are prevented contacting with 'the sidewall; of .the hole iin theipickng-arm. The closed endor bight of; the` inner loop' of lthe lug-strap tends to hold .the cushion or pad within the .chamber in thepicking-arm, and the pres# infpickiug tends to force' the cushion or gps. re securely home within the said Special means of holdingy the cushion or padin place vwithin the chamber jinsolne cases be employed.

'fprovide focuse, when desired, a cover 51- which issecured' over the upper portion 'of by a bolt 52 Aand nut 53, the lg-'Prtiqn of said cover -havinga slot 54 registers with the holes through the pokingf-arnnand cushionjor pad,which slot is designed toaccommodate the upper portio of the inner loopfof the lug-strap, The sai :sl'ot is wider horizontally than the hole throughthe-,cushion or pad, .so that there is' nolconta'ct' between theedges of the loop of thefz'lug-,Stap and the side-Walls of the said hole.g` The cover is provided withI a projecktiOgf; 455;,which extends into` l` `the hole 50 thrbi'l'ghi the cushion'or pad, and by engagefnent with the interior of the cushion or pad at the ftop of the said h ole affords support to the y'cushion or pad vertically; The sidewalls of the chamber inthe picking-arm are Vforlfnjed with 'interior shoulders 56,. 56, be-

low; the flower end of the cushion or pad.

These shoulders will support the cushion or pad vertically when the cover is removed, or "in case the projection above described 'as prov of or otherwise rei mved, or is omitted. l

l'he construction just described with refa d 16'to 2O is particularly well adapted fortheutilization of worn looppickers. Y

Figs.'; 21, 22, 231and 24 show a picking-arm 21" having at itslower end two sockets 57, 5,1', side'by side, but separated by a space 58 sufficiently'. wide to receive the inner loop of the lugstrap.,V The opening between the said sockets above. the sockets forms a passage for the -upp'erportionof the said loop. It is bridged about mid-height ofthe sockets by a crossbar A59 to secure the necessary strength. In these-id sockets is contained a cushion or pedi-42? consisting, for instance,

f One embodiment of the shuttle-checking featuresof the invention is shown applied 1n connection with the related parts of ay loom in Fig. 1, and ,certain details thereof are shown separately-in Figs. 2, 3, 25 and 26. In this instance the incline is fixedly combined with the picker-stick, and the con- Y tact-piece is combined with the` lug-strap, although this is note'ssential in the case' of all the forms of embodiment of this port-ioni of the invention. The said incline isshown at61 combined with the picker-stick in Fig.

1 and separately in Figs. 25 and 26..,TheA

acting surface of the incline-piece isI out-f wardly and downwardly inclined. The contact-piecev is here constituted by the cushion or pad 32 occupying the-bend or bight of the outer loop, 23, ofthe lug-strap', As' previ-f ously described, the said cushion or pad preferably isa worn-out picker, although this is not indispensable, inasmuch as the the incline. The incline-piece vis providedwith a down-turned stem, the lower portion of which is received within a socket 62, formed in the clamp-piece 5", as shown in Figs: 1, 2, and3, and secured therein by means of a clamping-screw 63. The straight lower portion of the `stem is of suliicient length to provide for an ample rangeof adjustment of the incline up and down. The incline-piece serves the additionalv function of a support for the outer portion of the 'lugstrap, by which the height of the said portion with,y relation to 'the picker-stick `.is determined. By adjustment of the inclinepiece up or down, the height at which the contact-piece may, be otherwise constituted-n lug-strap engages with the :picker-stick may picker-stick, and prevent springing of 'its ,1

Stem and vibration of the incline, a collar 65 is arranged to engage with the upper' portions of the said stem and hold such portion firmly. HThis collar is shown in place upon the picker-stick in Fig. 1, and separately in y Figs. 27 and 28, Sheet 2. It lits around the .picker-stick and the said stem-portionand binds the two tightly together. To facilitate the application of the colla-r it is made Witlran opening 66, Fig.. 28, at one side of vsuiiiciently `large dimensions tov-:permit the upper portion of the taperingapi'ckenstick,Mis o just below the laybeam,to pass therethrough.

Fig. 31, Sheet 4, shows a construction in which a strip of metal is bent intoV an open triangular form, as at 74, the top of which constitutes the incline. thek strip are brought together, with flat sm'- faces thereof in contact with each other, such extremities together forming the stem of the incline-piece, and being. clamped between the upper portion of the clamp-plate .'51b and the outer edge of the picker-stick. At is a collar like that of Figs. 1, 27 and 28, encircling the stem of the incline-piece and binding the incline-piece firmly in place against the outer edge of the picker-stick, and at 6,8 is a block of leather between the said stem and the said edge of the picker- .stick to-,absorb 'the vibrations of the stem.VVV

The said Fig. 31 shows a stop for preventing the outer end of the lug-strap from lifting, comprising a` stirrup 75 passing over through the opening of the triangular por-- kktion of the incline-pice. Any tendency of the lug-strap to rise will be prevented by engagement of the said pin or projection with the under side of the top portion of the said incline-piece. The stirrup might be replaced by a single arm, and a similar stop might be employed in the'case of the construction shown in Fig.l 1, and be arranged to coperate with the laterally-projecting webs of the cam-pieces of Figs.V 29 and 30.

In some cases, the contact-piece which'coacts with'the incline may be applied to an intermediate portion of the length of the lug-strap. An instance is shown in Fig. 32, Sheet 4, in which the contact-piece 32, composed preferably of a piece of leather, vulcanized hber, or the like, is fastened by the` holt 2S and nut 29 of the clamping devices which join together the two loops of the lugstrap. The construction otherwiseis similar to that of Fig. 30, save that the incline extends upwardand inward at the inner edge of the picker-stick, and the incline-piece', 61", is formed with a horizontal surface 77, on which said contact-piece rests to support the lug-strap when. the ylatter occupies its normal position. A wedge' 78 is shown driven down between the outer part 4of the collar of The extremities of picker-stick, tf1y tighten the said eollar .upon thefpickertick.; This wed-ge in connection withnthe other constructions when the collar does not it upon the pickerstick as 'tightly as it should.

The incline-piece may he attached directly to the picker-stick itself. An 'instance of this attachment is shown in Figs. 33, 34 and 35, Sheet 5. In the construction of these figures the incline-piece 61 is mounted upon the' picker-stick by means of a metal strap 79, whichembraces the picker-stick, the free ends or ears of suehstrap being extended at the opposite sides of the heel-portion of the incline-piece. A bolt 8O passes throu h holes in the said free ends or ears and in t e said heel-portion between them, the threaded portion of the bolt having a nut 81 applied thereto. A doubled strip of leather, or other suitable material, marked, 82,v is placed between the outer edge'of the pickerstick and the heel of the incline-piece, to obviate injury to the said edge. A wedge 83 inserted inside the metal strap at the inner edgeY of the picker-stick serves to secure a tight fit of the strap, etc., upon the pickerstick. The surface `of the 'heel which' "is turned toward the picker-stick is 'eccentri' Lse cally formed, as shown in Fig. 34:,l so that any tendency of the outer end of the incline-pieceto sink will carry theilarger 'portion of the eccentric around toward the picke1.stick, the effect of which 'willbe to strainthe strap more tightly around they picker-stick. Hence if the strap is properly 'fitted to the picker-stick the outer `portion of the cam-piece cannot become depressed seas to improperlyl incline the wgorking surface thereof. At the time of slipping the 'collar and incline-piece down into place upon the picker-stick, the outer end of the incline-'- piece is turned upward so as to present the portion of least projection of the heel portion to the picker-stick. When they have l reached theproper place in the height ofA the picker-stick, the said outer end is turned downY into proper working position. This will cause the eccentricity of the heel-por? tion to act to draw the collar tightly against the picker-stick.

'In Fig. 36, Sheet 5, the stem of the .in-*f4L eline-piece 61 is clamped between the outer` edgeof the picker-stick andthe clamp-piece for the foot-end of the pickerstick,=the

collar 65 and leather block '68 being the same" as in the case of constructions whichhave been described. The lnclme-plece and its stem are formed of a strip or bar which 1s bent to the required shape to form the stem,v

the incline which coacts with thecontactniece of the lug-strap, Vand a horizontal surface 7.7 for supporting the outer endo' the lug-'strap when the pickerstick occupies its normalposition.

las

Inrth'e differentforms "of the checking arrangement the weightyof the llug-strap will bel' proportioned to secure the required checking action, and for an increase in the checking action the weight of the lug-strap 'may be increased.I Thismode of insuring the required checking efficiency is' best for looms'running at moderate or low speed. In

the'case'of high speed looms the use ofa heavy lug-strap has` certain practical objecti'ons. With'high-speed looms a spring may be employed to draw the lug-strap downward. This is illustrated in Fig. 36,

inxwhich thecontractingl spiral springB' has', its upper end engaged with an eye 85 in connectionwith the clamping devices by which the loops ofthe lug-strap arejoined together, and its lower endengaged with a. 86"'which is fastened by screw 5l to the socket' of the rocker or shoe.l Other forms 'and varrangements of springs may be employed. l

The inclinepiece may in some cases be v'supported by the yrocker-bed 6, as in Fig. f i 37,'Sheet 5, in which the incline-piece 61 l'is at the upper end of an arm 61 having its lower end fastened to the rocker-bed by a screw 61S, nut 61h, and washer 61. The said lower end is slotted vertically, at 61k, to provi'de for vertical adjustment of the inclinepiece. In this construction the inclinepiece does not swing with the picker-stick.

lhe-'contact-piece which is carried-.by the lug-strapgfor coperation with the incline is constituted by va disk or washer 32e on the lbolt 33 which holds the cushion or pad 32 inside the outer loop of the lug-strap. The 'said' disk`- or. washer is shown clamped vagainst vone outer side of the said loop by vthe nut 34 on said bolt. In the swinging movement-of the picker-stick the said disk or washerftrav-els along the incline. The incline-piece. isformed with an inwardly pro'- J'ectin'g evtensionv 61m along the upper edge of whicli-=the disk or washer travels when the lug-strap is' moved inwardly for -the pick, the aid'edge being shaped to support' thelug-strap at approximately thelsame point in the y.height of the picker-stick throughout the'sweep' 'of the latter. The incline-piece 61e preferably is yoke-shaped so as to extendl around at the rearas well4 as the front -ofthe picker-stick, and a second washer or disk isimounted upon the bolt 33 at the-rear side of the lug-strap. v

InA this construction of Fig. 37,'in the normalv 'position of thepicker-stick, lug

strap, etc., the disk or washer 32% carried by the lug-strap occupies a position low down on the incline. with the cushion or pad which occupies the iouter loop of the,

lug-strap close to thev picker-stick. lVhen the shuttle enters' the shuttle-box and drives the picker-stick ahead of it, the engagement of the' stick with the, cushion or pad carries -upon the end s first named. v l

the lug-strap outward, causingthe diskv or washer'to travel up the incline, whereby the required checking'ation is brought about.`
